Vulkan Memory Types 07 Sep 2025
Picking up the discussion on memory and caching: how does this all interact with an external processor such as a GPU? GPUs are an intersting addition to this discussion because their operation is very memory-bound and very very multi-core. They also run alongside CPUs. This makes things ...complicated.

Knowing that main memory is slow (relative to what otherwise goes on in the CPU), software can do a few things to run faster. These things all boil down to just "work with the CPU's cache and don't ever fight it".

Computers have both a superpower and a problem: they are physical objects. And what the laws of physics give in terms of the massive potential to do work in parallel, they take away in the speed-of-light limit and heat. All of this has to be engineered around.
